Application filed May 19,1914.

To all whom it may concern:

Be it known that 1, WILLIAM Nnss, a c 1t1- zen of the United States, residing at Sprmg Grove, in the county of York and State of ments in wrenches, the primary object of the same belng to provide a simple arrange- I -ment'of wrenches whereby the same may be easily and quickly converted from a pipe to a nut wrench, or vice versa.

A further object of the invention -1s to provide a wrench including a shank whlch has one of its sides formed with teeth, a yoke-shaped carriage being arranged upon the shank, the carriagehaving arranged between its sides and the edge of its ends a jaw, each of said jaws having the r adjacent faces formed with depressions which serve as bars for the trunnions provided upon the opposite ends of a worm screw which acts upon the threads or teeth of the shank so that the carriage may be moved longitudinally of the shank and sustained in such longitudinal position, and further whereby the carriage may be entirely re moved from the shank to position either of the heads carried by the carriage for cooperation with the fixed jaw of the wrench.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claim.

In the drawings:

Figure 1 is a side elevation illustrating a wrench constructed in accordance with the present invention, showing the carriage arranged upon the shank of the fixed jaw with the nut or bolt engaging head or jaw of the carriage disposed to cooperate with the fixed jaw of the wrench.

Fig. 2 is a similar view but showing the pipe gripping jaw of the carriage disposed to cooperate with the fixed jaw of the wrench,

Fig. 3 is a transverse sectional view on the line 0cr0 of Fig. 1,

Fig. l is a horizontal sectional view on the line g g of Fig. 2.

tionally U-shaped carriage,

Patented Apr. ,3, 1917.

Serial No. 839,568.

Fig. 6 is a perspective view of one of the jaws for the carriage. 7

Referring now to the drawings in detail, the numeral 1 designates a jaw which has formed therewith an angularly disposed longitudinally extending shank 2. The shank isfor the major portion of its length of an equal width and thickness throughout,

but the inner end of the said shank has its front and back edges reduced, so that the handle portion 3 of the said shank is of a lesser width than the shank proper. The shank has formed upon its front edge a plurality of spaced teeth 4.

The numeral -6 designates a cross secthe same being provided with parallel sides and a right angular connecting member for the sides, and is adapted to be arranged upon the shank 2 to slide freely thereon. The sides of the carriage 6 are provided with elongated substantially rectangular openings 7 the said sides being also provided with reduced openings or orifices through which pass removable securing members9, in the nature of small bolts, whlch also pass through similar openings provided in what I term the centrally arranged webs 10 of jaws 11 and 12 respectively. The jaw 11 has an outer straight face, and is adapted to cooperate with the jaw 1 when the wrench is employed upon square or rectangular articles, such as nuts, bolts and the like, and the shoulders 13, at the opposite sides of the webs 10 of each of the jaws 11 and 12 abut with the outer edges of the side members of the carriage 6, the webs 10 being of a width equaling the proper spaced distance between the said sides of the carriage, so when the jaws are secured to the carriage, the webs form spacing members for the sides thereof, as well as reinforcing members for thecarriage. By this arrangement it will be noted that the stress or strain delivered to either of the jaws will be imparted to the shoulders provided between the jaws and the webs-thereof and consequently delivered to the corner edges of the carriage so as to relieve the securing members from strain. The second jaw 12 has its engaging face angular and provided with teeth 14, and when the same is adapted to cooperate with the jaw 1, as shown in Fig. 2, the wrench is adapted for use upon cylindrical or rounded surfaces, such as pipes or the like. The

the teeth 4 of theshank 2. The projecting sides of the said screw 17 permit of the ready rotation of the same so that the carriage 6 may be moved longitudinally of the jaw l'upon the shank 2 to move one of the jaws 11 or 12 toward the jaw l, or to entirely remove the carriage from the shank to permit of the said carriage being reversed and; again arranged upon the shank in accordance with which of the jaws, 11 or 12,

is desired to be brought to operative position adjacent the jaw 1 of the shank.

It should be stated that the wrench is prii' marily adapted for comparatively light 1 28 work, and so the shank 2 will not be of any great length, and the carriage may thus be removed from the shank for a comparatively short while, reversed and again adjusted upon the shank without occasioning a great amount of trouble or other inconvenience. 1 From the above description, taken in connection with the accompanying drawings,

Copies of this patent may be obtained for the simplicity of the device, as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.

Having thus described the invention, what I claim is:

In a wrench, a stationary jaw having an angular toothed shank, a carriage comprising a substantially rectangular sheet of metal adapted to be bent upon itself to provide parallel spaced sides, and each of the sides having a registering rectangular opening, members comprising jaws having their sides depressed to receive the outer corners of the sides of the carriage, means for securing the said corners within the said (lepressions of the jaws to arrange the sides flush with the sides of the jaws, and a screw member having its ends provided with trunnions which are received in depressed bearings in the confronting ends of the jaws, said screw being arranged within the referred to openings in the sides of the carriage and adapted to cooperate with the teeth of the shank of the stationary jaw.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM NESS.
